Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together the flour, sugar, baking powder, cinnamon, and any additional spices.
Cut in the cold butter until the mixture resembles coarse crumbs.
Mix pumpkin puree and milk in a separate bowl. Gradually add this to the dry ingredients, stirring until just combined.
Turn the dough out onto a lightly floured surface, kneading gently and patting it into a circle about 1-inch thick.
Slice the dough into eight wedges and transfer them to the prepared baking sheet.
Bake for 15-20 minutes until golden and cooked through.
While cooling, mix powdered sugar with water or milk until smooth, then drizzle over the scones.
Enjoy your pumpkin scones with your favorite coffee!
